BURNER FOR INCANDESCENT GAS-LIGHTS.

SPECIFICATION forming part of Letters Patent No. 599,915, dated March 1,1898.

Application filed June 11, 1897. Serial No. 640,385. (No model.)

burner for incandescent gas-lights in which all the parts can be soconstructed that they can be readily assembled, being formed of integralpieces of metal, and in which the burner is constructed in such a mannerthat a uniform supply of gas and air to the mantle is obtained whateverbe the pressure of;

the gas; and the invention consists of an incandescent gas-burner inwhich the burner proper is provided with means for regulatingsimultaneously the supply of gas and air, so that a uniform proportionof-the gas and air mixture is supplied to the incandescent mantle forthe various gas-pressures.

The invention consists, further, of the peculiar construction of thegallery for supporting the chimney and cup and of the novel constructionof the burner-top, which also serves for the support of themantle-supporting rod.

The invention consists, further, of the special construction of thechimney and shade supporting uprights, and, lastly, of some details ofconstruction which will be fully described hereinafter and finallypointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of myimproved incandescent gas-burner. Fig. 2 is a horizontal section of thesame on line 2 2, Fig. 1,

showing a plan view of the chimney and cup supporting gallery. Fig. 3 isavertioal transverse section of said gallery, drawn on a larger scale,on line 3 3, Fig. 2. 'Figs. 4, 5, 6, and 7 are details showing theconnection of the uprights with the top ring, gallery, and burner. Fig.8 is a perspective view of the shade-supporting clip. Fig. 9 is avertical central sec tion through the burner portion proper, drawn on alarger scale. Fig. 10 is a top view of the burner proper. Figs. 11, 12,and 13 are details of the Valve for controlling the supply of gas andair 'to the burner. Fig. 14: is a horizontal section of the diaphragm bywhich a uniform supply of gas and air to the burner is circulated. Fig.15 is a modification showing the gas-supply as fixed, the air-supplyonly being regulated. Fig. 16 is an elevation, showing a modified formof my construction. Fig. 17 is a side View of the lower part of Fig. 16;and Fig. 18 is a top view of the valve, showing details of themodification.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the burner portion proper of myimproved incandescent gas-light, which is provided at its upper'end withan enlarged cylindrical mixingchamber A and at its lower end with avalve B for supplying the required proportionate quantity of gas and airto the mixing-chamber of the burner. A tubular shank A is arrangedbetween the mixing-chamber and the valve B, the upper end of the tubularshank being covered by means of a convex diaphragm a of wire-gauze,through which air and gas supplied to the tubular shank are compelled topass until they are thoroughly mixed on their way to the mixing-chamberA. The tubular shank A is formed of two sections, the

lower shouldered section supporting the valve B, while the upper sectionis formed at the lower end of the mixing-chamber, as shown clearly inFig. 9. The upper end of the mixing-chamber is closed by a diaphragm D,that is provided with tapering openings near its circumference, saiddiaphragm being applied by means of radial downwardly-bent stripsd tothe upper end of the mixing-chamber. The upper end of the mixing-chamberis provided with exterior depressions 01 into which the ends of thedownwardly-bent retainingstrips cl are sprung, so that the diaphragmD isfirmly held in position at the upper end of the mixing-chamber, as shownclearly in Figs. 9 and 10. The central portion of the diaphragm D ismade concave and may be provided at its center with adownwardly-extending socket d, that serves as a support for the rod m,on which the incandescent mantle M is supported. Instead of thisconstruction I prefer to secure to the upper side of the gallery G astud m for the mantle-supporting rod m. This stud is slitted nearly itsentire length and is grooved near its lower end, thus affording a springclamping action for holding the rod, whereby the rod may be easilyremoved when desired.

The valve B is constructed of a gas-supply tube, which is screwed to thelower end of the tubular shank A and of a stationary diaphragm b, thatis provided with small inletopenings. This gas-supply tube is providedwith a number of vertical slots g, into one of which a tongue it, formedon the periphery of the stationary diaphragm 1), extends, whereby saiddiaphragm b is locked to the gas-supply tube, as shown in Fig. 13.

Above the diaphragm b is arranged a main diaphragm B, the centralportion of which is provided with openings corresponding to thegas-supply openings, and the outer portion or rim b of which is providedwith a number of elongated openings b that open or close more or less anumber of curved radial air-tubes B that are for communication with theopenings b in the lower part of the tubular shank A as shown in Fig. 9.The movable web of the main diaphragm B is provided with a milledcircumferential rim 4', so that it can be readily taken hold of andadjusted into the required position, it being provided alongside of eachopening 12 with small projections or teats 19 that abut against thelower edge of the air-tubes B when the main diaphragm B arrives inentirely open or entirely closed position. The main diaphragm B isprovided with an annular opening g in its central portion, through whichproject the ends of the gas-supply tube formed by the vertical slots g.This opening is subdivided by a number of radial arms 9 which fitloosely into the spaces formed by said vertical slots of the gas-supplytube, as shown in Fig. 12, whereby the main diaphragm B is supported in.close contact with the stationary diaphragm b. By the partial rotationsof the central perforated web of the main diaphragm B and the exteriorperforated portion b of the same the gas-inlet openings, as well as theair-inlet openings, are simultaneously opened or closed, so that thesupply of gas and air to the burner is kept at the same proportionwhatever be the gas-pressure, whereby a better and more effective lightis obtained.

hen the burners are placed on chandeliers too high to be easily reached,the valve may be operated by providing a three-armed lever S, which ispivoted to a projection S on the gas-tube. The lever S is provided witha vertical arm S, located in the center thereof, which arm operatesbetween two cars S formed on the underside of the diaphragm B. Asuitable weightedchain is attached to each end of the lever S, by whichthe valve may be operated in the ordinary Well-known manner.

To the tubular shank A of the burner proper, below the mixing-chamber A,is applied a gallery G, which is made in one integral piece with itscup-supporting brackets 0, being preferably stamped from one piece ofsheet metal and provided with the required openings y, nicks y, andprojections 1 so as to form connection with the shade-supportinguprights F. The lower ends of the upright rods F are attached by a ringf to the shank of the burner, as shown in Fig. 3. The details ofconnection between the uprights F and the gallery G are clearly shown inFigs. 6 and 7 and permit the ready connecting of these parts whenassembling the difierent parts of the lamp. The uprights F are providedat some distance from their upper ends with recesses fandinwardly-projecting ribs f that retain a connecting-ring F said ribspassing over the inner surface of the ring F and holding it firmly inposition on the uprights, as shown clearly in Fig. 5. To the upper endsof the uprights F are applied the shade-supporting clips F which areprovided with oblong perforations in the upper clip portions andinclined outwardly-extending arms f as shown in detail in Fig. 8, saidclips being slipped over the upper ends of the uprights F until they aresupported on the shoulder formed in the same.

In order to prevent side drafts from striking the air-mixing chamber andrendering the light unsteady, a draft-guard I'I, Fig. 1, may be sleevedupon the tubular shank A This draft-guard is substantially cup-shapedand is stamped out of thin sheet metal and extends upwardly,encompassing the lower portion of the air-mixing chamber A.

The modification shown in Fig. 15 differs from the principalconstruction in forming the gas-supply orifices in a transversepartition which is fixed orintegral within the gassupply tube near itsupper end. The main diaphragm B is sleeved upon the upper portion of thesaid gas -supply tube and rests upon a ledge formed thereon, so as torevolve freely about the same. In this construction the separatestationary diaphragm 1) (shown in Fig. 13) is not required. Theair-supply only is regulated, and this is accomplished in the samemanner and by the same construction as above described in the principalform.

My improved incandescent gas-lamp has many advantages, among which maybe mentioned the quick and convenient assembling of the parts, owing tothe fact that the various parts are easily detachable and by reason oftheir construction can be quickly assembled and locked in position. Thenovel construction of the valve permits the perfect regulation of thesupply of gas and air to the burner proper regardless of the greater orsmaller gas-pressure, so that the proper proportions of air and gas areautomatically obtained and the supply both of the air and gassimultaneously regulated by the turning of one valvediaphragm. Thesimple construction by which the mantle is supported in the burnertoppermits the ready removal of the mandrel for the purposes of cleaning,repairing, or renewing the same. The various parts are produced byspecial dies in such a manner that they can be easily and quicklyassembled with little hand labor, thusmaterially reducing the cost ofmanufacture.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A burner for incandescent gas-lights, composed of amixing-chamber, a burner-top having outlet-openings, a tubular shank below the mixing-chamber and provided with air-openings, aregulating-valve at the lower end of the tubular shank, saidregulating-' valve being formed of a movable diaphragm provided withgas-openings and air-openings, a stationary diaphragm provided withgasopenings, and stationary air-tubes registering with the air-openingsof the shank and those of the movable diaphragm, substantially as setforth.
